(54) Sleep evaluation device


(57) - A sleep evaluation device 1 is provided with a respiration detection unit 7 that detects changes in respiration and outputs respiration signals. CPU 6 generates six primary parameters indicating sleep states based on the respiration signals and four secondary parameters based on the primary parameters. The secondary parameters are linearly independent of one another. Evaluation unit 20 computes a sleep score indicating the degree of the quality of sleep by multiplying each of the four secondary parameters by second coefficients and totalizing results of the multiplications. Results of the evaluations are displayed on display unit 4.
